So my Elan has failed its MOT due to weeping of one of the compensator valves. Mine have 2/15 1434 engraved on them and I've found some on ebay (see link below) but they have different numbers on them. Would I be able to use these?

I know the other option is to recondition the valve with new O rings (I've heard that this is problematic and I have no idea what size they are) or to buy the redesigned valves but they are so expensive on SJsportscars and they don't have the brake pipes I would need.

This is my daily driver so I need to get this sorted and retested asap, any help would be very appreciated.
